Welding Speed Short Arc (SSA) Process in synergic mode

Note: The list of available programs depends on the power source.
In synergic mode, the welding voltage is not set directly by
user. The correct welding voltage will be set by the
machine's software.
Optimal voltage value is related to the input data:

Wire Feed Speed, WFS.
Speed Short Arc
comprehensiveness during steel and stainless welding.
Up to fast arc control during increasing the wire feeding
speed, standard short arc naturally shifts to SSA mode,
extending the range of the short arc to higher current and
prevents the globular mode, which is characterized by
high spattering and higher energy than short arc.
Advantages:

Reduction of welded material distortions (less energy
introduced into the weld).

Wider range of feeding speed with maintaining the
short arc.

Reduction of spattering in comparison to standard CV
mode.

Fume reduction in comparison to the standard CV
mode (up to 25% less).
If it is needed, the welding voltage can be adjusted by the
Right Control [17]. When the right control is rotated, the
Right Display [14] will show a positive or negative bar
indication if the voltage is above or below the optimal
voltage.

Pinch
Pinch controls the arc characteristics during short-arc
welding. Increasing Pinch Control results in a crisper arc
(more spatter) while decreasing provides a softer arc (less
spatter).

Adjust range: from -10 to +10.
